Kyriacos C. Markides (born November 19, 1942) is a professor of sociology at the University of Maine.  He has written several books on Christian mysticism including Mountain of Silence, Gifts of the Desert, and Inner River.  The following excerpt is from the book Gifts of the Desert, and gives what I consider an enlightened interpretation of John 14:6b. The context of the excerpt below is a QA session following a lecture on Eastern Orthodox spirituality.

“Just as I was about to thank the participants for their attentiveness and end the workshop, a woman who had earlier identified herself as a “born again Christian” raised her hand with marked intensity.

‘Christ taught that only through him can one go to the Father. How should we understand this statement?’ Given my audience, it was the most challenging question I faced.

I had the feeling that she needed affirmation for her beliefs and consciously or unconsciously wished to prompt me into declaring that only Christians will inherit heaven. Feeling somewhat uneasy, I reflected for a few seconds. I knew that, whatever answer I could possibly come up with, someone might feel offended or excluded. ‘Furthermore,’ I added, ‘I am not a biblical scholar who can offer an authoritative exegesis of scripture. I am certainly not a theologian.’ Inwardly, I asked for guidance as I placed my left hand in my pocket and fiddled with a komboschini [a string of black knots made out of wool that the Athonite monks use for ceaseless prayer]. Father Maximos had given it to me after pulling it off his own hand. It offered me a sense of security at that moment.

‘Look,’ I replied finally. ‘There are two possible ways to answer your question. The first is to interpret that passage in the New Testament literally, the way many Christians today would interpret it. In this sense, nobody who is not a baptized Christian can be saved. Some denominations would even make the claim that only through their specific community can a human being find salvation. This is, let us say, an ‘exoteric’ belief shared widely among fundamentalist Christians. It is a belief, however, that divides people, raising serious questions about God’s fairness and love for all his creatures. The typical objection is this: Does it mean that the billions of people who are not born Christians and who may have never heard of Christ will be lost for eternity? From a more esoteric, ‘inner Christian’ perspective such a conclusion seems misguided, to put it mildly. It denies the possibility of salvation to the overwhelming majority of the human race. Surely this could not have been Christ’s intention when he made that statement.’

I was encouraged by the facial expressions of the participants and continued. ‘Why then don’t we make an attempt to interpret that statement in a more inclusive way? Why don’t we try to look at it in terms of its possible inner meaning? I believe the Gospel of John offers us guidelines to answer questions like yours. Christ, according to the Gospel, is ‘the true Light, which lighteth every man that cometh into the world’ [John 1:9]. Do you agree?’ After she nodded I continued. ‘Well, that says it all. Every human being has the Christ within his or her very nature. Furthermore, we are told that Christ is total and unconditional Love. Is it not, therefore, reasonable to conclude that whoever wishes to go to the Father, i.e., God, must attain the state of absolute and selfless love that Jesus embodied? If Christ is Love, then anyone who reaches the state of purification reaches the Father. No one can go to the Father, therefore, outside of total and selfless love. This is, I believe, the true spirit of the Christian message and this is what I understand the great saints of Christianity have taught either explicitly or implicitly.”
